Visor Down says that the UK price for the 390 will be 4,495 pounds. (roughly $7,100 US). What does the Ninja 300 sell for in the UK? I think if it were offered in the US at $5K, it would take a huge chunk of the market. At $10K, enthusiasts would still rave about it, but nobody would actually buy it. In the $7k to $8k range, it gets a little dicey for me. Soon enough, people are going to be able to get Ninja 300's for $5.5k OTD almost everywhere, and closer to $5K OTD in some places. Would that same buyer be willing to pay $2k - $3k more?
